Ponder how destructive solar power is: It only takes 13% solar to push a small grid to the edge
A little bit of solar power causes mayhem on a perfectly good grid.
NT Electricity Grid Map (Click to enlarge) Darwin is 1,300 km or 800 miles in a straight line from Alice Springs.
The Renewable Crash Test Dummy Country is aiming to be using 82% renewable electricity by 2030, but instead of making sure this works on a small scale at any one of our remote microgrid locations, where electricity is expensive to start with, we thought we’d do the experiment on the whole nation instead.
So it is “sobering” to see how this fails at Alice Springs. If there was a place on Earth that is well suited to wind and solar power, it surely is Alice Springs which is 1,200 kilometers from the Northern Territory’s main electricity grid. Surrounded by a million square kilometers of largely uninhabited arid land, if we can’t plaster enough solar panels and windmills here to support a town of 25,000 people with no heavy industry to speak of, where can we?
Yet the bare truth is that solar […]
By Jo Nova California was the Land of Solar Panels at the top of the Magic Subsidy Tree but that boom went bust
If solar panels were actually cheap and useful, everyone could have them, they’d pay for themselves, and there would be no point where the panel-party would grind to a halt. But if they were expensive, made something useless, and their product became toxic to the grid itself the government would have to artificially subsidize them to get them onto the grid in the first place, and then pop its own bubble before the bubble popped the grid. And so that time has arrived in California and there is carnage in the market.
The Duck has quacked
In a strange coincidence the Californian government cut the payments for solar-powered-electricity by 75% last year, and sales of solar panels fell to a quarter of what they were a year ago. That’s a “to” not a “by”. One in five solar contractors has already left the market. Careers and businesses — gone.
The new price for solar-powered-electricity is probably slightly closer to the true market value, which is almost zero, or even less for holy-green electricity at noon. The Duck […]

South Australia survived the big scary sunny day yesterday, but had to shut off solar power and throw all those sacred green electrons into a thousand open circuits.
Yet again, another spooky voltage spike appeared, suddenly leaping from 245 to 257 volts in less than three minutes and shaking down any impertinent solar panels. That was at 10am. From then on, despite the growing sunlight, the combined solar output of South Australia stayed flat at around 1.2GW. Compare this to last week — before the safety cord to Victoria broke — then, solar generation was peaking at 2.1 GW. So the great renewable wonderland is managing to keep the lights on, but nearly a billion watts of solar power is sitting uselessly on rooftops and in fields every sunny day at lunch time.
This is not the cheap and efficient golden path to the future, but the Bolshevik elephant that eats your retirement plans. Despite the oversupply of unreliable generation, yesterday the state was using fossil fuels to supply between 20% and 80% of their electricity.
Mark Jessop recorded the voltage and commented: “Lovely sunny day here in islanded SA, which of course means @SAPowerNetworks has bumped […]

With all the calm language of a paid ad agency, the ABC is breathless because an esoteric measure called “minimum operational demand” has hit a record or two. This glorious moment may have only lasted 30 minutes, and it isn’t actually a useful thing, but it’s a “record”.
In fact, “minimum operational demand” is a grid management headache, not a badge of honor. It’s the midday moment when solar panels all work — and it’s becoming such a problem that two states in Australia have said all new solar panels need “smart” controllers so that the guys in the central control rooms can turn the darn things off. That’s how good it is.
Renewable energy records tumble around the country as rooftop solar power soars
by ABC Energy Propaganda Reporter, Daniel Mercer
Soaring power production from households and businesses with rooftop solar panels has sent records tumbling across Australia as output from fossil fuels falls to all-time lows.
The record so-called minimum operational demand excludes the power generated by consumers with their own solar panels, which met 92 per cent of South Australia’s overall needs at one point on October 17.

Watch this space. The Western Australian election is four weeks off and the new young Liberal (“Conservative”) opposition leader has just made this a “climate change” election and launched himself to the left of the Labor Party by suggesting the state can close all government run coal plants by 2025.
Epic loss coming. The opposition leader may even lose his own seat (Dawesville, in Mandurah, held by only 0.8%). The National Party and minor conservative parties could do well from the aftermath.
Aiming for political correctness in a politically incorrect state?
WA political landscape turned on its head as Liberals outline renewable energy policy
[ABC News] One major party is making the case that renewables are the way of the future, the other is warning they will cripple jobs and send power prices skyrocketing. …it is politics as usual in Australia for the past decade. Except in this case, it is the WA Liberal Party calling for coal to be tossed aside and wind and solar to take its place, with Labor blasting the idea as “reckless”.
The Liberal Party were on a hiding to nothing before this announcement. The local Labor Premier hit 90% […]
Western Australia is a giant experiment: Even the Energy Experts are saying solar is jeopardizing the grid — it’s “dumb”
Watch this space — blackout coming, 3 years and counting…
The Western Australian grid is a separate island from the rest of the nation. It’s roughly a 2.5 GW system for 2.5 million people. WA is getting into trouble faster than nearly anywhere else. Solar PV is now up to …. something larger than 850MW (which is the size of the coal fired generator). The ABC doesn’t tell us what the real figure is (according to the AEMO it’s around 1300MW, and growing at 120MW a year). There are no interconnectors to rescue WA, just the taxpayer or hapless electricity consumer.
Unreliable solar is now the largest single generator in the Western Australian grid. It’s not only bad because there are no other states to dump the excess energy on, or to save the state, but despite the vast size nearly everyone lives within 100 kms (60 miles). So when the sun peaks for one it nearly peaks for all. When the clouds roll over, especially when those nice north-south aligned fronts roll in, it covers most of the […]
UPDATE: Commenters point out that there is more to this story.
Shutting down Eraring (which is a term the operations manager there used) makes no sense at all, and they are probably talking of a “hot idle”, though they do that already, so it’s not a “totally new operating model” as described. Read their comments. Graeme No. 3. TonyfromOz and Lance below.

Solar power destroys efficiency of the rest of the system
All this will sit around doing nothing? Eraring Coal Plant, NSW
The Eraring power plant produces up to 2,880 MW. That’s 20 per cent of Australia’s largest state’s (NSW) electricity and about the same (percentage-wise) as the entire fleet of 94 wind farms in Australia plus our couple-of-million solar panels. It’s been running four giant turbines almost non-stop for 35 years. But the intrusion of subsidized mass solar energy arriving in the middle of the day means it is now testing whether it should stop and start the turbines during lunch time. These turbines weigh hundreds of tons, and spin at 3,000 rpm.
There are hundreds of small and large hot metal parts with operating temperatures above 500 degrees C. As the temperature changes, all of […]
Solar installations are rapidly accelerating in Australia, surging in the last quarter by an extraordinary 482MW. This is partly due to rapidly rising electricity costs, but in the last quarter, especially amplified by an extra $2250 subsidy in Victoria which adds to current subsidies like the SRES (RET) which already cover around half the cost of installation.
This is obviously a market destroying practice but will be hailed as evidence that solar power is “surging” due to “falling prices” and “increasing demand”. More fake news.
In the land of the Renewable-Crash-Test-Dummy we’re hitting the death spiral. Every installation costs non-solar owners more (with the tally at $200pa and rising fast) and there are fewer non-solar owners left to pay. Obviously, the whole market has to be changed to ensure that solar owners pay a fair share of networking and backup costs.
If solar power was cheap, useful or competitive, it wouldn’t need the subsidies. Instead, the nation keeps adding more useless infrastructure and wondering why the price of electricity is rising.

Crash Test Dummy Update: Data analysis thanks to Tom Quirk
In the South Australian experiment total wind power capacity is now far above the average state demand most hours of the day. This effectively destroys any economic case for cheap baseload power (I hear that was the aim). This fleet of unreliable generators is being supported by forced subsidies through power bills from all around Australia. Sadly, despite this rain of money falling in SA, those funds end up with renewable investors, not South Australian consumers who pay some of the highest rates in the world.
These legislated subsidies have fed so much wind power that sometimes the state produces more power than it can use. That excess power will be exported, but may or may not be actually useful at whatever time it happens. Unless it happens at peak-time, it will be eating into the efficiency of baseload providers in other states. Like an infection, inefficiency and underutilization of infrastructure spreads…
This volatility appears to make freak wholesale price spikes more likely. Quirk calculates that one hot January day last year was so wildly expensive in South Australia it added $2/MWh to the entire years average wholesale cost. Can’t […]
Ladies and Gentlemen, Australia is now romping in as Star-Crash-Test-Dummy in the renewables stake.
Proportionally, we have more uncontrolled solar roof top generators than any other nation. We’re in uncharted territory: about 20% of houses in Hawaii and California have Solar PV, but in Western Australia, it’s 25%. In Queensland it’s 30% and throughout Australia we are adding 100MW a month and it’s like a whole new coal fired station every year (except it doesn’t work most of the time).
Strap yourself in! This is more useless infrastructure than anywhere else on planet Earth. The only time solar PV panels provide something we might need is at afternoon tea time in summer when airconditioners are on. So for three quarters of the year they provide electricity when we don’t need it, and for three quarters of every day they don’t even work. The rest of the time they burn capital, increase the blackout and fire risk and sit there collecting dust and hail stones.
Electricity at the wrong time is not just wasted, it’s a burden
Too much electricity bumps up the grid frequency and voltage, potentially damaging equipment and risking blackouts. Obviously we have to “manage” this flood of […]
